De-misting a sand blaster window

Feb 12, 2010 14 Replies

My Guyson sand blasting cabinet is excellent, but the perspex window constantly mists up externally from my breath. Especially in the current cold weather it becomes a right pain, but even in more normal times it's a problem. I have thoughts of installing some sort of blower to give a cross draught, possibly with a heater, but cannot find anything small enough not to be cumbersome.



Any suggestions welcome, but lets not start a heavy breathing thread!

Isn't there something that you can spray on to prevent misting like motorcyclists use to prevent their visors fogging? I'm thinking vaseline, but probably wrong...

I have a couple of 24v dc 0.33A tangential blowers. Outlet is 210mm wide by 25mm high. Fan is about 40 diameter. Overall mount area about

25 x 100 weight 400g. If any good you can have one for the postage. They are ex photo copier. I am in Cheltenham.

I would have thought a computer fan would do the job. Something off an old power supply or cpu. My video card even has a diddy one mounted on it.

A little neat washing up liquid rubbed on stops the misting for quite a while. Isn't that what posh divers use on the inside of their goggles - common ones use spit :-)

In the early days of high speed experimental jets the Yanks used Drene shampoo. I wonder if it's still available :-)) Henry

I have some of the hydrophobic liquid (I can't remember the name and the label is missing, so not a good sales pitch) designed for car windscreens, shower doors, binoculars etc. If you want I can stick a small vial in the post for you to try.

washing up liquid may work just as well, that's what I used to use on my visor.

Andrew Mawson formulated the question :

Something like a motorcycling mask, so your breath is diverted down towards your neck, rather than straight forwards at the visor?

Washing up liquid, wiped on then polished off is what I use on the visor.

Are you calling me common?

No they're gnomes

Oh gnome they're not!
